The morning shot where the winding knob broke the film was about 1 hour into -20C morning temperatures. The rewind break was about 1 hr into -5 to -10C.
I'll give it another go soon enough, I think, with the camera in my coat when not shooting, and winding and rewinding *very* gently....
Sounds like the cold then. Keeping the camera warmer between shots could certainly help. If it's any consolation I have to do this with my "most modern" M9 too...
